Abstract
Description
- The present invention relates generally to a rotor for a torque sensor and, more particularly, to a rotor for a torque sensor, configured to improve a mechanical coupling force with respect to a jig in a process of adjusting a torque center, thus enabling a fine adjustment.
- Generally, a vehicle is configured to change a driving direction by manipulating a steering wheel connected to a wheel. However, if resistance between the wheel and a road is large or there is an obstacle to steering, a manipulation force is decreased, thus making it difficult to rapidly manipulate. In order to solve the problem, a power steering system has been used. Such a power steering system includes a power unit to manipulate the steering wheel, thus reducing a manipulation force.
- In order for the power unit to assist in manipulating the steering wheel, it is necessary to measure torque acting on a steering shaft. Thus, several types of devices are used to measure torque of the steering wheel. Among them, a device detecting torque by measuring a magnetic field relative to a magnet coupled to the steering shaft has been widely used because it is more economical.
- A general steering structure includes an input shaft to which a steering wheel is coupled, an output shaft coupled to a pinion engaging with a rack bar of a wheel, and a torsion bar connecting the input shaft and the output shaft.
- If the steering wheel rotates, a rotating force is transmitted to the output shaft, and the wheel changes its direction by interaction between the pinion and the rack bar. Here, the larger resistance is, the more the input shaft rotates. Hence, the torsion bar is twisted. A degree to which the torsion bar is twisted is measured by the torque sensor using the magnetic field.
- When the steering wheel is not manipulated, the torque sensor maintains a central position. If a set center is erroneous, there occurs a difference in auxiliary steering force between left and right sides during a manipulation of the steering wheel. Thus, as for the power steering system, it is very important to adjust the center of the torque sensor.
-
FIG. 1 is a perspective view showing a conventional rotor for a torque sensor. - A
rotor 1 having amagnet 2 is coupled to an input shaft of a steering system, and a stator (not shown) is coupled to an output shaft. - If the torsion bar is twisted by a difference in rotation amount between the input shaft coupled to the
rotor 1 and the output shaft coupled to the stator, themagnet 2 and the stator rotate relative to each other. At this time, opposite surfaces between themagnet 2 and the stator are changed, so that a magnetization value is changed, and thereby torque may be measured using the change in magnetization value. - The
rotor 1 includes a sleeve 4 coupled to an outer circumference of the input shaft, and a yoke 3 coupled with the sleeve 4 to allow themagnet 2 to be coupled to an outer circumference thereof. - In order to adjust the center of the torque sensor, there has been used a method of holding a predetermined portion on the outer circumference of the sleeve 4 by a jig and then rotating the
rotor 1 by a frictional force. - However, such a method is problematic in that the jig rotates the outer circumference of the sleeve by the frictional force, so that there is a relatively strong possibility that the jig will slip from the sleeve, and it is difficult to finely adjust the center.
- Accordingly, the present invention has been made keeping in mind the above problems occurring in the prior art, and an object of the present invention is to provide a rotor for a torque sensor, capable of more precisely performing a center adjusting operation.
- According to one aspect of this invention, there is provided a rotor for a torque sensor, the rotor comprising: a rotor body including a sleeve coupled to a rotating shaft, and a yoke protruding from an outer circumference of the sleeve; a ring-shaped magnet coupled to an outer circumference of the yoke; and an anti-slip structure formed on the rotor body and partially coming into contact with a jig during a rotating process for adjusting a torque center, thus preventing slipping between the rotor body and the jig when a rotating force is transmitted. Thus, slipping between the jig and the rotor body is prevented to enable precise transmission of the rotating force, so that accuracy is improved during fine adjustment of the torque center.
- Further, the anti-slip structure may include a serration formed on an upper end of the yoke in a circumferential direction thereof, the serration coming into contact with a lower end of the jig during the rotating process for adjusting the center, thus transmitting the rotating force from the jig to the yoke. Thus, the jig is brought into contact with the yoke, thus allowing the rotating force to be reliably transmitted when the center is adjusted.
- Further, the anti-slip structure may include a hole formed in the outer circumference of the sleeve, and a protrusion formed on the jig is inserted into the hole, thus transmitting the rotating force from the jig to the sleeve. Thus, the jig comes into contact with the sleeve, thus allowing the rotating force to be more reliably transmitted when the center is adjusted.
- Further, the anti-slip structure may include a knurled portion formed on the outer circumference of the sleeve, and the jig partially comes into contact with the knurled portion of the sleeve, thus transmitting the rotating force from the jig to the sleeve. Thus, a frictional force between the sleeve and the jig is improved, thus allowing the rotating force to be reliably transmitted.
- Further, the anti-slip structure may include a depression formed downwards from an upper end of the sleeve, and a protrusion formed on the jig is inserted into the depression, thus transmitting the rotating force from the jig to the sleeve. Thus, a mechanical coupling force between the sleeve and the jig is excellent.
- Meanwhile, according to another aspect of this invention, there is provided a rotor for a torque sensor, the rotor comprising: a rotor body coupled to a rotating shaft; a ring-shaped magnet disposed to protrude to an outer circumference of the rotor body; and an anti-slip structure formed on the rotor body, wherein during a rotating process for adjusting a torque center, a jig comes into contact with the outer circumference of the rotor body or an upper portion of the magnet, and the anti-slip structure is formed on a surface making contact with the jig, thus preventing slipping between the jig and the rotor body. Thus, a frictional force between contact portions of the jig and the rotor is improved, so that the accuracy of a center adjustment is improved.
- A rotor for a torque sensor according to the present invention constructed as described above is advantageous in that a frictional force is increased at a portion coupled with a jig when a center of the rotor is adjusted, thus providing various structures that enable precise transmission of a rotating force, and thereby permitting a fine adjustment of the torque center, therefore improving operational reliability of a steering system.

-
FIG. 2 is a perspective view showing a rotor for a torque sensor according to the present invention. - A
magnet 20 is shaped like a ring, and is generally coupled to an outer circumference of an input shaft of a steering system to be rotated along with the input shaft. - Further, a stator (not shown) is connected to an output shaft to be rotated along with the output shaft.
- It can be understood that torsion occurs when there is a difference in rotation amount between the input shaft and the output shaft due to resistance of a wheel. The difference is measured using a magnetic field as described above. Of course, the
magnet 20 may be connected to the output shaft, and the stator may be connected to the input shaft. - The
rotor 10 includes a rotor body and the ring-shaped magnet 20. The rotor body includes a ring-shaped yoke 30 that protrudes outwards from a lower end of asleeve 40 taking a shape of a hollow cylinder. Themagnet 20 is coupled to an outer circumference of the rotor body. To be more specific, themagnet 20 is coupled to an outer circumference of theyoke 30. - As described above, an inner circumference of the
sleeve 40 is connected to a rotating shaft of the steering system to be rotated along with the rotating shaft. - Further, the
yoke 30 is coupled to thesleeve 40 to support themagnet 20 and thereby rotate along with thesleeve 40. However, theyoke 30 may be integrated with thesleeve 40. - Preferably, the
magnet 20 comprises two or more magnet segments that are to be connected to each other. To be more specific, a plurality of arc-shaped magnet segments forms the ring-shaped magnet 20. - The
rotor 10 is coupled to the rotating shaft of the steering system by fitting therotor 10 over the rotating shaft starting from a lower portion of thesleeve 40, and a torque center is adjusted by an additional device, a jig. - According to the present invention, the rotor body has a shape to allow rotating power to be reliably transmitted between the jig and the
rotor 10, thus preventing slipping between the rotor body and the jig when the torque center is adjusted, and thereby enabling a precise adjustment. Such a shape may be implemented by various embodiments of anti-slip structures, for example, a structure for increasing a frictional force between contact portions, such as a serration or a micro groove, or a structure for providing a mechanical coupling force, such as a hole or a recess. - Thus, as a first embodiment for increasing a rotating frictional force, a
serrated portion 31 is formed on an upper end of theyoke 30. - The
serrated portion 31 is circumferentially formed on an upper surface of theyoke 30 protruding outwards from a lower end of thesleeve 40, thus having an uneven shape. It is preferable that the uneven shape be a wedge shape to allow theserrated portion 31 to be easily coupled to the jig. - In this case, a lower end of the jig is brought into contact with an upper end of the uneven
serrated portion 31 to transmit a rotating force. - Further, as a second embodiment for increasing a frictional force, an uneven portion may be formed on the upper surface of the
yoke 30. - The uneven portion may be formed by fine line-shaped grooves, or may comprise a single protrusion or a plurality of protrusions. In an example of
FIG. 4 , the uneven portion is formed by a plurality of diagonal line-shaped grooves. - Similarly to the first embodiment, the second embodiment provides a frictional force when a lower end of a jig comes into contact with the upper surface of the
yoke 30. - Further, as a third embodiment for increasing a frictional force, a
hole 42 is formed in a side surface of thesleeve 40. - Preferably, the
hole 42 is formed in the side surface of thesleeve 40 making contact with the jig, and a protrusion is formed on a portion of the jig to be fixedly inserted into thehole 42. - According to a shape of the jig, a single hole or a plurality of holes may be formed in the side surface of the
sleeve 40. - Meanwhile, the
hole 42 may be replaced by a recess, a fine line-shaped groove, a single protrusion or a plurality of protrusions. - Further, as a fourth embodiment for increasing a frictional force, a depression may be formed in an upper end of the
sleeve 40. - The depression is depressed downwards from the upper end of the
sleeve 40. In this case, the jig comes into contact with the upper end of thesleeve 40 and includes a protrusion that may be inserted into the depression, thus maximizing a frictional force therebetween. - The above embodiments for increasing the frictional force may be selectively applied, but two or more embodiments may combine with each other.
- For example, both the
serrated portion 31 of theyoke 30 and thehole 42 of thesleeve 40 may be formed, and the jig may be disposed to be in contact with both the upper surface of theyoke 30 and the side surface of thesleeve 40. In this case, since a frictional force between contact surfaces of therotor 10 and the jig is maximized, a center adjusting operation can be precisely performed. -
FIG. 3 is a perspective view showing a coupling of a jig and a rotor for a torque sensor according to an embodiment of the present invention. - While the torque center of the rotor for the torque sensor is adjusted, the lower end of the
jig 50 comes into contact with the upper surface of theyoke 30 in a state in which therotor 10 is coupled to an outer circumference of the rotating shaft. - Since the
serrated portion 31 is formed on the upper surface of theyoke 30 and a serrated portion is also formed on the lower end of thejig 50 to correspond to a shape of theserrated portion 31, a rotating force can be precisely transmitted between theyoke 30 and thejig 50. -
FIG. 4 is a perspective view showing a coupling of a jig and a rotor for a torque sensor according to another embodiment of the present invention. - Unlike the embodiment of
FIG. 3 , a jig 51comes into contact with the side surface of thesleeve 40. - A diagonal line-shaped
knurled portion 43 is formed on the side surface of thesleeve 40. Theknurled portion 43 increases a frictional force at a contact portion between thesleeve 40 and thejig 51, thus allowing a rotating force to be precisely transmitted. - Of course, as described above, the
knurled portion 43 may be replaced by ahole 42 or a protrusion. - According to the above embodiment, the jig comprises two long bars. However, the jig may be selected from various shapes including one bar and a ring, as long as it may transmit a rotating force to the rotor and adjusts the center.
- The present invention provides various structures for precisely transmitting a rotating force by increasing a frictional force at a portion coupled with a jig when a center of a rotor of a torque sensor is adjusted. Thus, a fine adjustment of the torque center is possible. This improves operational reliability of a steering system.
- The present invention has been described with reference to embodiments and the accompanying drawings. However, it is to be understood that the scope of the invention is not limited by the specific embodiments and drawings except as defined in the appended claims.
